Sticky Revision: |
* implemented portamento mode and solo mode (a.k.a 'mono mode'): all modes can be altered via standard GM messages, that is CC5 for altering portamento time, CC65 for enabling / disabling portamento mode, CC126 for enabling solo mode and CC127 for disabling solo mode * fixed EG3 (pitch envelope) synthesis which was neutral all the time * configure.in: do not automatically pick optimized gcc flags if the user already provided some on his own (as CXXFLAGS)
* extensive synthesis optimization: reimplementation of EGs and LFO(s), removed synthesis parameter prerendering and the synthesis parameter matrix in general, splitting each audio fragment into subfragments now where each subfragment uses constant synthesis parameters (everything's still very buggy ATM)
* design change: using now one sampler engine instance and one disk thread instance for all sampler channels that are connected to the same audio output device (and are using the same engine type of course) * added EngineFactory / EngineChannelFactory to remove the annoying build dependencies e.g. of the lscpserver to the actual sampler engine implementations * bumped version to 0.3.0 (current CVS state is still quite broken, previous, stable CVS version was tagged as "v0_2_0" and is also available as source tarball)
* introduced 'synthesis mode' to reduce the amount of code and conditionals for the current synthesis case in the main synthesis loop * support for MMX and SSE(1) in the core synthesis algorithms (CPU feature detection at runtime, only x86 so far)
updated copyright header for 2004
* completely restructured source tree * implemented multi channel support * implemented instrument manager, which controls sharing of instruments between multiple sampler engines / sampler channels * created abstract classes 'AudioOutputDevice' and 'MidiInputDevice' for convenient implementation of further audio output driver and MIDI input driver for LinuxSampler * implemented following LSCP commands: 'SET CHANNEL MIDI INPUT TYPE', 'LOAD ENGINE', 'GET CHANNELS', 'ADD CHANNEL', 'REMOVE CHANNEL', 'SET CHANNEL AUDIO OUTPUT TYPE' * temporarily removed all command line options * LSCP server is now launched by default
